CAST-IRON GAR-WHEEL.

Specification of Letters Patent No. 6,026, dated January 9, 1849.

To all whom it may concern:

Be it known that we, ALBERT T. CONVERSE and XVILLIAM S. CoonnY, of thecity of Norwich, in the county of New London, State of Connecticut, haveinvented a new and Improved Form of Cast-Iron Wheels for Railroad Carsand Engines; and we do here by declare that the following is a full andexact description of the same, reference being had to the annexeddrawings and model accompanying.

.We give to the rim of our wheel, the same form which is usually appliedto car wheels, the periphery being inclosed in an iron chill when cast.

Our improvement consists, in making a wheel with solid hub, having twosets of arms placed in such position, that their outsides are nearlyparallel with, and form part of the sides of the wheel. It willbeperceived that the position of the arms are at right angles, withthose usually employed in the construction of armed wheels, therebyobviating the important objection which has been madeheretofore,inasmuch as a perfectly uniform chilled surface on the tread of thewheel, could not be obtained, with the arms attached transversely to theinside of the rim, owing to the portions of the tread opposite the endsof the arms, being to a certain extent, annealed, by the presence of agreater thickness of metal at those parts. lVe also greatly increase thestrength of the Wheel, by uniting each arm of both sides with itsopposite fellow, as delineated in the drawing. vacant spaces between thearms, by inserting in the mold, dry sand cores, in a manner well knownto founders, and make the wheel entire, at one casting.

Figure lis a plan of the side of the wheel which has the flange, (theother side being nearly similar) showing the shape of the arms, h, ofwhich, there are eight on each side, directly opposite each other,and'connected together by the tie piece, shown at C. Fig. 2 is asectional view of the wheel, as it would appear if divided at the line AB. 9 9 shows a longitudinal section, through the center of the arms. clcl are braces on the inside, by which the same are strengthened. 0 isthe connecting piece, which ties each arm to its opposite fellow; E, thehub, which is made without the divisions necessary, in casting otherarmed wheels. The hole to receive the axle, is indicated at F. I J

What we claim, and desire to secure by Letters Patent, is

The mode of connecting the arms of one We form the inside, and also theside with those of the other side, when formed substantially in themanner before mentioned.
